Yesterday, Gabe Aul of Microsoft confirmed on Twitter that anyone who tests the latest version of the Windows 10 Technical Preview will get Windows 10 for FREE when it is released on July 29th of this year. To be eligible for the free copy of Windows 10, you must download the latest version of the Windows 10 Preview (Build 10130 or newer), install it, and sign in with a Microsoft account linked to the Windows Insider program. If you do all this before July 29th, then you will automatically receive the final version when it releases. If you are not already a member of the Insider program, you can get more information on Microsoft’s website.
